Dear Editor:Give our BICE people a break. The Wal-Mart operation was probably just a training exercise for the newly merged agents who've never worked immigration enforcement. Those arrests hardly qualify as highlighting our nation's acute dependence on illegal aliens. They do tend to point out, however, the result of years of both public and official indifference to enforcing immigration law. Look on the bright side. If those illegal workers cannot be replaced without the assistance of immigration attorneys, then you should welcome such enforcement efforts. As you point out that's your bread and butter.
